Subpage delete not working with pagetable plugin

[kiahr]

On a page titled Artists, I am using the pagetable plugin to show child pages.

The Artists blueprint has delete: false, while the child blueprint is set to delete: true.

When I click the three dots on the side of the child pages (within the table) to reveal drop down, the delete is greyed out.

          mypagetable:
            headline: Artists
            type: pagetable
            templates: artist
            image: 
              query: page.cover.toFile
              cover: true
            columns:
              lastName:
                label: Last Name
                text: '{{ page.lastName }}'
                width: 1/4
              firstName:
                label: First Name
                text: '{{ page.firstName }}'

Any idea what could be causing this?

Thanks
